 MSCollapsibleTableViewController
 ================================
 
+<h2>Overview</h2>
+
 This is a basic subclass of UITableViewController to allow the collapsing of sections in a table view.
 
 The main class is the MSCollapsibleTableViewController class. The rest of this repo is just the sample project using it.

 There is a "toggleCollapseSection" method exposed on the header to actually collapse/expand a specific section.
+
+
+<h2>Implementation</h2>
+
+It is very easy to implement:
+
+1) Copy the "MSCollapsibleTableViewController.m" and ".h" to your project.
+
+2) Make your existing (or new) TableViewController inherit from the "MSCollapsibleTableViewController" class.
+
+3) Implement the "numberOfRowsInSection" delegate method for your table view as per usual, except you will need to write
+it in a block and set the "numberOfRowsInSectionBlock" property on the super class. Then call the super's version of
+"numberOfRowsInSection".
+
+Example:
+
+
+        - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
+        {
+            self.numberOfRowsInSectionBlock = ^(NSInteger section) {
+                if (section == 0 || section == 1)
+                {
+                    return 1;
+                }
+                
+                return 2;
+            };
+        
+            return [super tableView:tableView numberOfRowsInSection:section];
+        }
+
+4) Now just call "toggleCollapseSection:" with the section number you want to toggle the collapse / expand method on.
+
+Example:
+
+        [self toggleCollapseSection:1];
